Explanation:
We are given an Hint that:
A backslash \ in a string acts as an escape character, such as with a newline \n. So, to print an actual backslash, escape that backslash by prepending another backslash.
An Example : The following prints a single backslash: System.out.println("\\");
The main objective here is to use a Java code to interpret the above (1) Output this tree and (2) Below the tree.
So Using a Java code to interpret the Program: ASCII art ; we have:
public class AsciiArt {
public static void main(String[] args) {
// TODO Auto-generated method stub
//Draw Tree
System.out.println(" *");
System.out.println(" ***");
System.out.println(" *****");
System.out.println("*******");
System.out.println(" ***");
//output cat
System.out.println();
System.out.println("/\\\t/\\");
System.out.println(" o o");
System.out.println(" = =")
System.out.println(" ---");
}

Answer: provided in the explanation section
Explanation:
Network’s vulnerabilities:
Vulnerability is a weak spot in your network that might be exploited by a security threat. Risks are the potential consequences and impacts of unaddressed vulnerabilities. In other words, failing to do Windows Updates on your Web server is vulnerability.
Regularly scheduled network vulnerability scanning can help an organization identify weaknesses in their network security before the bad guys can mount an attack. The goal of running a vulnerability scanner or conducting an external vulnerability assessments is to identify devices on your network that are open to known vulnerabilities without actually compromising your systems.
The overall objective of a Vulnerability Assessment is to scan, investigate, analyze and report on the level of risk associated with any security vulnerabilities discovered on the public, internet-facing devices and to provide your organization with appropriate mitigation strategies to address those discovered vulnerabilities.
Network topology issues:
Coverage Topology
Coverage problem reflects how well an area is monitored or tracked. The coverage and connectivity problems in networks have received considerable attention in the research community in recent years
Geographic routing
Geographic routing uses geographic and topological information of the network to achieve optimal routing schemes with high routing efficiency and low power consumption
Port Numbers
Port Numbers While IP addresses determine the physical endpoints of a network connection, port numbers determine the logical endpoints of the connection. Port numbers are 16-bit integers with a useful range from 1 to 65535.
Port numbers are assigned by an organization called IANA and ports are allocated to various needs to avoid confusion.
Ports are classified into 3 main categories.
Well Known Ports (Port numbers 0 - 1023)
In a client-server application, the server usually provides its service on a well-known port number. Well-known port numbers are a subset of the numbers which are assigned to applications. According to RFC1700 [5], well-known port numbers are managed by the Internet Assigned Numbers Authority (IANA). They used to be in the range from 1 to 255, but in 1992 the range was increased up to 1023.
Registered Ports (Port numbers1024 - 49151)
Such ports are used by programs run by users in the system.
In addition to the well-known ports below 1024 there are more port numbers assigned to applications but are located anywhere from 1024 to 65535.
Private or Dynamic Ports (Port numbers 49152 - 65535)
Private ports are not assigned for any specific purpose.
Discuss the concepts of well-known ports and give a brief description of the most commonly used ports: 20, 21, 23, 25, 53, and 110.
Commonly Used Port Numbers
The following port numbers are unofficial list of commonly used for linux/unix based servers.
20&21 TCP FTP (File server protocol)
FTP is one of the most commonly used file transfer protocols on the Internet and within private networks. An FTP server can easily be set up with little networking knowledge and provides the ability to easily relocate files from one system to another. FTP control is handled on TCP port 21 and its data transfer can use TCP port 20 as well as dynamic ports depending on the specific configuration.
23 TCP/UDP Telnet
Telnet is the primary method used to manage network devices at the command level. Unlike SSH which provides a secure connection, Telnet does not, it simply provides a basic unsecured connection. Many lower level network devices support Telnet and not SSH as it required some additional processing. Caution should be used when connecting to a device using Telnet over a public network as the login credentials will be transmitted in the clear.
25 TCP/UDP SMTP (for sending outgoing emails)
SMTP is used for two primary functions, it is used to transfer mail (email) from source to destination between mail servers and it is used by end users to send email to a mail system.
53 TCP/UDP DNS Server (Domain name service for DNS request)
The DNS is used widely on the public internet and on private networks to translate domain names into IP addresses, typically for network routing. DNS is hieratical with main root servers that contain databases that list the managers of high level Top Level Domains (TLD) (such as .com). T
110 TCP POP3 (For receiving emails)
POP version 3 is one of the two main protocols used to retrieve mail from a server. POP was designed to be very simple by allowing a client to retrieve the complete contents of a server mailbox and then deleting the contents from the server.

//variable to hold number is assigned any random value
static long num=123;
static int sum=0;

public static void main(String[] args) {
s = sumDigits(num);
System.out.println("The sum of the digits of "+num+ " is "+s); }
}
OUTPUT
The sum of the digits of 123 is 6
Explanation:
1. The variables to hold the number is declared as long and initialized.
2. The variables to store the digits of the number and the sum of the digits are declared as integer. The variable, sum, is initialized to 0.
3. The method, sumDigits(), is defined which takes a long parameter and returns an integer value. The method takes the number as a parameter and returns the sum of its digits.
4. Inside method, sumDigits(), inside the do-while loop, the sum of the digits of the parameter is computed.
5. Inside main(), the method, sumDigits(), is called. The integer value returned by this method is stored in another integer variable, s.
6. The sum of the digits is then displayed to the console.
7. All the variables are declared outside main() and at the class level and hence declared static. The method, sumDigits(), is also declared static since it is to be called inside main().
8. In java, the whole code is written inside a class since java is a purely object-oriented language.
9. In this program, object of the class is not created since only a single class is involved having main() method.
10. The program can be tested for any value of the variable, num.
11. The file is saved as Test.java, where Test is the name of the class having main() method.

Answers
Answer:
Top Secret, (A,B,C)
Explanation:
Solution:
Some information are known to be sensitive, and has a higher level of classification.
Examples for such levels are: Secret, Top secret ,Unclassified and Confidential, and Unclassified. all users of the system has a level of clearance. fro a user to be able to gain access to document, he or she must have posses a level of the document.
Now, this is governed by two rules which is stated below:
No user can have access to any information that is considered higher than their level of clearance.
Secondly, a user can write to files only that contains an equal level or lower of his clearance level, this is to stop what is called the write down effect.
It is important to note that ABC, categories determine what type of access is permitted.
Now, for the given example, since, Bob and charlie cannot read it, which shows that the file must be of top priority or importance, then Bob and Charlie needs clearance to the file,the file 2 is considered a top priority.
Therefore, the File 2 is classified as a Top Secret, (A,B,C)

Suppose two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, Sketch the waveform produced by A when “$” is sent. Also mention the OSI layer that is responsible for this.
Answers
Answer:
Physical / Data link layer
Explanation:
If two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, the data would be transmitted if the network is clear but if the network is not clear, the transmission would wait until the network is clear.
The Open Systems Interconnection model (OSI model) has seven layers each with its own function.
The physical layer is the first layer responsible for data transmission over a physical link. The data packets are converted to signals over a transmission media like ethernet cable.
The data link layer is the second layer in the OSI layer responsible for transmission of data packets between nodes in a network. It also provides a way of detecting errors and correcting this errors produced as a result of data transmission.

Assume the following variable definition appears in a program:
double number = 12.3456;
Write a cout statement that uses the setprecision manipulator and the fixed manipulator to display the number variable rounded to 2 digits after the decimal point. (Assume that the program includes the necessary header file for the manipulators.)
Answers
Answer:
cout << setprecision(2)<< fixed << number;
Explanation:
The above statement returns 12.35 as output
Though, the statement can be split to multiple statements; but the question requires the use of a cout statement.
The statement starts by setting precision to 2 using setprecision(2)
This is immediately followed by the fixed manipulator;
The essence of the fixed manipulator is to ensure that the number returns 2 digits after the decimal point;
Using only setprecision(2) in the cout statement will on return the 2 digits (12) before the decimal point.
The fixed manipulator is then followed by the variable to be printed.
See code snippet below
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
// Initializing the double value
double number = 12.3456;
//Print result
cout << setprecision(2)<< fixed << number;
return 0;

Answers
Explanation:
Evaluating the solution is the last step of the problem solving process.
For each of the descriptions below, perform the following tasks:
i. Identify the degree and cardinalities of the relationship.
ii. Express the relationships in each description graphically with an E-R diagram.
a. A book is identified by its ISBN number, and it has a title, a price, and a date of publication. It is published by a publisher, which has its own ID number and a name. Each book has exactly one publisher, but one publisher typically publishes multiple books over time.
b. A book is written by one or multiple authors. Each author is identified by an author number and has a name and date of birth. Each author has either one or multiple books; in addition, occasionally data are needed regarding prospective authors who have not yet published any books.
c. In the context specified in 2a and 2b, better information is needed regarding the relationship between a book and its authors. Specifically, it is important to record the percentage of the royalties that belongs to a specific author, whether or not a specific author is a lead author of the book, and each author's position in the sequence of the book's authors.
d. A book can be part of a series, which is also identified as a book and has its own ISBN number. One book can belong to several sets, and a set consists of at least one but potentially many books.
e. A piano manufacturer wants to keep track of all the pianos it makes individually. Each piano has an identifying serial number and a manufacturing completion date. Each instrument represents exactly one piano model, all of which have an identification number and a name. In addition, the company wants to maintain information about the designer of the model. Overtime, the company often manufactures thousands of pianos of a certain model, and the model design is specified before any single piano exists.
f. A piano manufacturer (see 2e) employs piano technicians who are responsible for inspecting the instruments before they are shipped to the customers. Each piano is inspected by at least two technicians (identified by their employee number). For each separate inspection, the company needs to record its date and a quality evaluation grade.
g. The piano technicians (see 2f) have a hierarchy of reporting relationships: Some of them have supervisory
responsibilities in addition to their inspection role and have multiple other technicians report to them. The supervisors themselves report to the chief technician of the company.
h. A vendor builds multiple types of tablet computers. Each has a type identification number and a name. The key
specifications for each type include amount of storage space and display type. The company uses multiple processor types, exactly one of which is used for a specific tablet computer type; obviously, the same processor can be used in multiple types of tablets. Each processor has a manufacturer and a manufacturer's unique code that identifies it.
i. Each individual tablet computer manufactured by the vendor (see 2h) is identified by the type identification number and a serial number that is unique within the type identification. The vendor wants to maintain information about when each tablet is shipped to a customer.
j. Each of the tablet computer types (see 2h) has a specific operating system. Each technician the company employs is certified to assemble a specific tablet type—operating system combination. The validity of a certification starts on the day the employee passes a certification examination for the combination, and the certification is valid for a specific period of time that varies depending on tablet type—operating system combination.

For this lab you will write a Java program that will run a simple math quiz. Your program will generate two random integers between 1 and 20 and then ask a series of math questions. Each question will be evaluated as to whether it is the right or wrong answer. In the end a final score should be reported for the user.
This is a sample transcript of what your program should do. Items in bold are user input and should not be put on the screen by your program.

In a horse race, the odds that Romance will win are listed as 2 : 3 and that Downhill will win are
1:2. What odds should be given for the event that either Romance or Downhill wins? (3 mks)
QUESTION FOUR
Answers
Answer:
The odds for the event that either Romance or Downhill wins is 11/4
Explanation:
The odds that Romance will win is 2: 3
The odds that Downhill will win is 1:2
[tex]P(event) = \frac{Odd(event)}{1 + Odd(event)}[/tex]
Where P(event) = Probability that an event occurs
Odd(event) = The odds that an event occurs
Calculate the Probability that Romance wins, P(R):
[tex]P(R) = \frac{2/3}{2/3 + 1} \\P(R) = 2/5[/tex]
Calculate the probability that Downhill wins, P(D):
[tex]P(D) = \frac{1/2}{1/2 + 1} \\P(D) = 1/3[/tex]
Calculate the Probability that either Romance or Downhill wins, P(R or D):
P(R or D) = P(R) + P(D)
P(R or D) = 2/5 + 1/3
P(R or D) = 11/15
[tex]P(R or D) = \frac{Odd(R or D)}{1 + Odd(R or D)} \\\\11/15 = \frac{Odd(R or D)}{1 + Odd(R or D)}\\[/tex]
[tex]\frac{11}{15} + \frac{11}{15}[ Odd(R or D)] = Odd(R or D)\\\\\frac{4}{15}[ Odd(R or D)] = \frac{11}{15}\\\\\\Odd(R or D) = \frac{11}{15} * \frac{15}{4}\\\\Odd(R or D) = 11/4[/tex]
2-3 Calculating the Body Mass Index (BMI). (Programming Exercise 2.14) Body Mass Index is a measure of health based on your weight. It can be calculated by taking your weight in kilograms and dividing by the square of your height in meters. Write a program that prompts the user to enter a weight in pounds and height in inches and displays the BMI. Note: One pound is 0.45359237 kilograms and one inch is 0.0254 meters. Hint: Convert the pounds entered into kilograms also convert the height in inches into meters Example: If you entered in pounds your weight as 95.5 and your height as 50 inches then the calculated BMI is 26.8573 FYI: BMI < 18.5 is underweight BMI >
Answers
Answer:
weight = float(input("Enter your weight in pounds: "))
height = float(input("Enter your height in inches: "))
weight = weight * 0.45359237
height = height * 0.0254
bmi = weight / (height * height)
print("Your BMI is: %.4f" % bmi)
Explanation:
*The code is written in Python.
Ask the user to enter weight in pounds and height in inches
Convert the weight into kilograms and height into meters using given conversion rates
Calculate the BMI using given formula
Print the BMI
Continue to develop the site content as directed in milestone 4. At this point, at least 3 of the pages for the site should be completed. Use the knowledge gained in this week's lecture and Lab to create a user feedback form. Include all necessary controls (text boxes, radio buttons, check boxes, text areas, dropdown lists, and buttons) to allow the user to effectively interact with the form. You can choose the type of input control for each question, but your feedback form will have at least five feedback questions. Use CSS to control the layout of the form. Include reset and submit buttons with the form. The reset button should clear the form and the submit button should load a "Your information has been received" page. Move all site and page level styles to an external CSS file. Upon completion of this step, zip up all of the files for the site into one single file and submit the file.
